Answer:
Reset
Explanation:
Git reset is a powerful and time saving tool. It allows you to go back to the previous version of your code.
It becomes handy when after adding a new bunch of code results in bugs then you can roll back to the earlier commit.
HEAD is basically a reference to the current commit. Whenever you update your code a commit is created and HEAD shifts to the latest commit.
This way we can go back to any commit that we want without any difficulty or hassle.
